Drum plug and faucet lock



June 10, '1930. T. c. NUNES I DRUM PLUG AND FAUCET LOCK Fild March 2s, 1928 INVENTOR Tony (iNLmflS BY Q) l9 ATTORNEY Patented June 10, 1930 s'rres PATET oerice norm 0. NUNES, or nuenson, CALIFORNIA DRUM PLUG AND FA'UOET LOCK Application filed. March 28 1928. Serial No. 255,401.

This invention relates to attachments forfaucet in one end. The plug is sealed when the drum is shipped from the refinery but m after the seal is once broken there is nothing to prevent the plug from being subsequently removed by anyone. As a result considerable of the liquid in the drums is frequently pilfered by parties who remove the plug and siphon the liquid out which of course can easily be done even if the faucet is locked. Since such drums are frequently left out in the open where they are accessible to anybody, it is practically impossible to prevent such pilfering and the loss to the owner in the aggregate is frequently considerable.

The principal object of my invention is to provide an attachment to be applied to the drum plug and faucet which when properly attached will prevent either the faucet being opened or the plug removed.

The device also serves as a wrench for unscrewing the plug when necessary as when providing the air vent when drawing liquid from the faucet.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of 0 the following specification and claim.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Fig. 1 is a perspective view of my attachment shown as applied to a drum in its locked position.

Fig. 2 is a side elevation of the attachment as in position on a drum.

Referring now more particularly to the characters of reference on the drawings, the

numeral 1 denotes the drum of standard form having on top a tapped boss 2 in which a screw plug 3 removably fits, and a dispensing faucet 4: projecting outwardly from one end of the drum near the bottom. The faucetl of. the type shown here, which is standard, has a transversely orificed turn- 'ing handle member 5 on its outer end.

My lock attachment comprises a horizontal bar 6 to extend over the top of the 00 drum from one end thereof to the plug, and having a square head 7 at the plug end to snugly lit in the usual socket provided in the plug. The plug is drilled through from the bottom of the socket to receive a stud 8 which is screwed into or formed with the head 7 and which is clamped to the plug by a nut 9 on its lower or inner end. A suitable gasket 10 is preferably placed between the outer flange of the plug and the boss 2, 7 to prevent the evaporation of the liquid if such is of a volatile character.

At its opposite end the bar is provided with transversely spaced eyes 11 to receive the upper end of a vertical bar 12 and between is a pivotal pin 13 connecting the bar and eyes. The bar 12 normally hangs down of its own weight and at its lower end is flattened as at 12 so that its side face is parallel to the end of the drum, said flatso tened portion being provided with a vertical slot 14- to fit over the faucet handle 5. Said bar also has an eye 15 below the slot and projecting outwardly relative to the bar to provide a handle whereby the bar may be easily raised and lowered. lVhen the bar is in this position a padlock 16 of ordinary character may be engaged with the orifice in the faucet handle outwardly of the bar. It will therefore be seen that with the attachment thus mounted the faucet cannot be opened and the plug cannot be turned. When the padlock is removed, however, the bar 12 may be immediately raised clear of the faucet, and the bars in 9 their outstretched position or folded over onto each othermay then be used as a wrench to loosen and unscrew the plug.

The bars are preferably connected together in such a manner that when the bar 12 is folded over onto the bar 6, said bars will then lie in close and parallel relationship to each other as indicated in Fig. 2,

thereby making a very compact device when removed for storage or shipment.

From the foregoing description it will readily be seenthat I have produced such a device as substantially fulfills the objects of the invention as set forth herein. 7

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claim.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

A locking device for the plug of a drum, said plug having a non-circular socket in its head, comprising a rigid bar, a headdepending from one end of the bar and non-turnably fitting into the socket, a bolt projecting into the head from the under side of the plug to rigidly connect them together, and a locking bar hinged onto the outer end of said first named bar.

In testimony whereof I afiix my signature.

TONY C. NUNES.
